1.13.2 🦕 Sunday Links... Neanderthals x 2, Bad Dreams, Fuel Cell Trains, Fast Battery Charging

Were the Flintstones Neanderthals? Apparently in the first issue of the Flintstones comic book, Mr. Slate gets Fred to hire Neanderthals because they don't know the meaning of money. So they co-existed. With that cleared out of the way, this Sunday email has two science stories about Neanderthals that I found interesting. Plus a fascinating story about Amazon warehouse workers figuring out how to get rare paid time off, as well as a story about hydrogen fueled trains, Earth's magnetic field, and more. Hope you find them of interesting and useful.
